Kummersdorf is the name of an estate near Luckenwalde at 52°05′N 13°20′E / 52.083°N 13.333°E / 52.083; 13.333, around 25 km south of Berlin, in the Brandenburg region of Germany. Until 1945 Kummersdorf hosted the weapon office of the German Army which ran a development centre for future weapons as well as an artillery range.
In 1929 the Army Weapons Office in Berlin wanted rockets for military purposes: in 1931 the test range at Kummersdorf took over the development of liquid fuel rockets type A1, A2 and A3 under the direction of Walter Dornberger. Wernher von Braun was at Kummersdorf from 1932 and developed a liquid fuel rocket in which the propellant was a high percentage of alcohol and liquid oxygen. He used this in his first experimental firing. In 1934 he fired successfully his second rocket, the A2, from the Frisian island of Borkum. On 16 July 1934, Dr Kurt Wahmke and 2 assistants were killed and another assistant injured during a fuel test of a premixed hydrogen peroxide/alcohol propellant when the fuel tank exploded.
